ltIEiNS FOP. PURIFYING WASTE OIL.

Specification of Letters Patent.

'1'0 all whom it may concern:

Be it known that l. CARL ALBERT limros Armin-Yr, a subject of the King of Sweden, and. resident of livillel ickeiagen. Gottenborg, in the Kingdom of Sweden. ltlv't invented certain tune-xeuste Oil new and useful ments in ii'lczms for Purifying W from Steam-Engines and the Like. of which the following is a spccification reference being had therein to the aecompanyiin; drawi ll -ing.

This invention. relates to moan-l -n' purifying wastooil from steam engines and the like and distributing: the same in purified condition to the ral parts of the engine to be lubricated.

The said oil is czuigg'ht in a tank or receptaclc of suitable form placed under the cu .m in question. From the said tunic the oil is transferred in a suitable nninner to (he purifying apparatus itself and. having been purified in thosznueit is transferred in controllable quantities and in an entirely automatic manner to-ihc parts of ti engine to be lubricated. The said purifying appa-- rutusconsists of a. tank divided into three special Qllllll'lbt'lS. situated one above the other. In the upper cl'lan'ibei. a pinityiir; box is suspended, provided with vertical filters. l.hei.n'1piu.'o oihhuviugp Htil through the said filters is drawn bywicl s over into the upper chan'iber. This provided with heating tubes and with a plurality of filters. The oil is heated in the chamber lust mentioned to 40 to 55 cent. and pass through the said filters and is then transferred tothe lower chamber of the tank. which is pro vided with inlets for water 1" well as" for stean'i. The oil is heated in i .c said chamber to to (35 cent. and is washed by means of a solution of conuron salt. From the lower chamber the oil 't'orced by the pressure exerted upon the some by the oil in the upper chamber, into the intern'iwliato chamber, passing through a double tiltcl. Separating the chamber and internm'liate the lower ciiauibcr and eliciting the final purifying operation. From the intermediate chamber the purilied oil then ted auto n'iuticully by special mensurii'lg devices to the ditlcrcut parts of the engine in be lubricated. Consequently. as seen 't'ri-wu the above, the purityi'ug operation consist? in the caught oil being first tiltcr luthun llllited to 40 to cent. then liltere-zl again,

thereupon washed by means oi 'ater and common salt (a solution of common salt), then heated to 50 to (35 cent. and finally filtered v in the accompanying drawings a plant is shown arranged in accordance with this invention and adapted to sea-steam engines.

Figure l is a front view of the purifying tank and Fig. 2 is a vertical section of the ilurifying tank.

The purifying apparatus comprises a tank 5 to which a pipe 4 leads from a waste oil receptacle (not shown herein). This tank 5 is divided into three chambers ll, l6, 17. in the upper chamber'll of the tank a box 12 is suspended, into which the oil is led through the pipe 4. The said box has double walls 13. 14, vertical filters 13 forming the inner wall. After the oil has passed through the said filters it is drawn up by wicks 15, which are mounted in the space between the filters and the wall 14- und from which wicks it drops into the upper chamber 11 oil the tank.

The upper chamber 11 and the intermediatechamher 16 areseparated by a solid bottom 15. In the upper chamber 11 two single filters 19 and 20 are mounted in a detachable manner. The chambers 16 and 17 are separated by a double filter 21. In the upper chamber 11 a steam pipe 22 is provided for heating the oil said pipe being connected with a pipe 23, which passes through the lower chamber 17. The chambers ll, 17 communicate through a pipe 24., provided with a cock or valve 25, operated by means of a wheel 26, and it is provided with a strainer 27. The oil, having passed through the-filters 15), 20, passes through the said pipe 24k and is spread in the lower chamber 17 by the strainer 27. In the said chamber the oil is subjected to a washing operation as well as a heating operation. The washinn operution is effected by means of common salt put into the chamber and water, introduced through a pipe 28, having a branch 2! leading to the upper chamber 11, and the heating of the chamber '17 to 50 to 05 cent. effected by the steam pipe 23. Owing to the pressure from the oil in the upper chamber li the oil in the lower chainher 17 is forced upward through the double filter 21 and enters the intermediate chamber 16, from which it distributed by automatically operatingmeasuring and lubricating mechanisms 30 into pipes 31 leading to the several parts of the engine to be lubricated.

The filters 11) and 20 and the bottom plate 18 can be taken out for cl aning from the top of the tank 5 after a cover 232 and the box 12 have been removed. The double filter 21. on the other hand is mounted in a frame which is inserted from the side of the tank. Thermometers 33, are provided to indicate the tmnpcrature in the chambers 11 and 17 and gageglasses 34, 3tare provided to indicate the levels of the oil in chambers it and 1t respmtively. ()il can be drawn off through a cock 35 for direct. lubrication if nec ary.

The measuring and distributing mechanisms 30 may be of any suitable construction, well known by those skilled in the art. For that reason they are not particularly described. The said mechanisms are caused to operate by spindles 52, 52, which are rotated by a suitable mechanism as, for instance, a ratchet wheel and pawl mechanism driven by the engine) the ratchet wheel 5i being fixed on the spindle 52 and the spindles 52 connecteddoy a gearing 53, 53.

Ha ring now described my invention, what I claim as new and desire to secure by Letters Patent. is:

1. In an apparatus for purifying waste oil, a purifyingtank divided into upper, lower and intermediate chambers, a purifying box in the upper chamber, means for supplying waste oil to said box, a filter in said box, wicks for drawing the oil from said box into the upper chamber, filters insaid upper chamber, upper to the lower the lower a pipe leading from the chamber, a filter between and intermediate chambers and l l l l 4 t t i It i l l l means for distributing the the intermediate chamber.

In an apparatus for purifying waste oil, a purifying tank divided into upper, lower and intermediate chambers, a purifyin box in the-upper chamber, means for supplying waste oil thereto, a filter in said box, wicks for drawing the oil from said box into the upper chamber, filters in said upper chamber, a pipe leading from said upper chamber to the lower chamber, a filter between the lower and intermediate chambers, means for suppiying heat to the oil within the upper and lower chambers and means for distributing the purified oil from the internnuliate chamber.

2: In an apparatus for purifying waste oil, a purifying tank divided into upper, lower and intermediate cln mbers, a purifying box in the upper chamber, means for feeding the waste oil thereto. a iiher in said box, wicks forfeedingg the oil from the box into the upper chamber, filters in said chambers, 21 pipe leading from the upper chamber to the lower chamber, a filter between the lower and intermediate chambers. means for supplying heat to the oil within the upper and lower chambers, means for introducing a solution of common salt into contact with the oil in the lower chamber and means for distributpurified oil from \fi tnesses:
